摘要
在林火蔓延模拟过程中,为技术基础林火蔓延模型模拟空间精度评价是一个十分重要的问题。以林火蔓延模拟、地理信息系统和计算机图形学为技术基础,以林火蔓延的边界位置、面积和轮廓形状为主要指标,提出了一套林火模型模拟空间精度的评价方案,并通过模拟实验验证了该方案的可行性。结果表明,这一方案可以满足林火蔓延模型模拟空间精度评价的需要,为多模型林火蔓延模拟中模型的选择提供了依据。
Space accuracy evaluation of forest fire spreading model is very important in the process of forest fire spreading simulation.This paper integrated the knowledge of forest fire spreading simulation, geographical information system and computer graphics,and put forward a solution for space accuracy evaluation of forest fire spreading model based on the three key characteristics of fire field boundary:location,area and shape.A simulation experiment was executed to verify the feasibility of the solution.The result shows that the solution can satisfy the needs of space accuracy evaluation of forest fire spreading model and provide the basis for the model evaluation in forest fire spreading simulation.
